Cadmium | Chemical elements

Cadmium was discovered in 1817 by Fredrich Stromeyer. Cadmium’s name derives from the Greek word "kadmeia" and the Latin word "cadmia". Cadmium’s melting point is at 320.9 °C (594.05 K, 609.62 °F) and its boiling point is at 765.0 °C (1038.15 K, 1409.0 °F).

Top 9 interesting facts about Cadmium

  1. Cadmium is chemically similar to zinc and mercury.
  2. Cadmium is bluish-white, soft, malleable, resistant to corrosion, and ductile metal.
  3. Cadmium is a byproduct of zinc production.
  4. Cadmium’s use is decreased due to its toxicity.
  5. Cadmium is composed of eight naturally occurring isotopes, two of them are naturally radioactive (113-Cd and 116-Cd) and three of them are stable (110-Cd, 111-Cd, and 112-Cd).
  6. Cadmium is a rare metal making up just 0.1 ppm of the Earth’s crust.
  7. Cadmium’s top producers are China, South Korea, and Japan.
  8. Cadmium is used in batteries, electroplating in aircraft industry, and a small amount in nuclear fission and different laboratory experiments.
  9. Cadmium’s use and supply in Europe is restricted due to its dangerous effects on environment and human health.
